11 Claims. (Cl. 299-2 3) This invention relates to an air humidifying,cleansing and sterilizing device, and while the invention may havevarious applications, it is particularly designed for use in connectionwith a radiator such as the heating radiators commonly used in dwellingsand other buildings. The importance of having such a device is beingrecognized more and more by architects and heating engineers and suchdevices are now being installed in large numbers.

In such a device using absorbent sheets it is desirable to have ahumidifying unit which can be easily made and'assembled and which can beeasily transported and installed, whether in the original structure oras a replacement.

It is an object of this invention, therefore, to provide a simple, neatand efiicient humidifying device adapted to be conveniently supportedupon or in a radiator.

It is another. object of the invention to provide a humidifying devicecomprising a simple and eflicient absorbing unit which can be easilymade and assembled and easily transported and installed.

It is more specifically an object of the invention to provide ahumidifying device comprising a receptacle adapted to contain liquid,and having spaced, narrow, longitudinally extending portions with aconnecting portion at one end adapted to be disposed upon or in a.radiator, together with an absorbent unit comprising absorbent sheetsdisposed in said spaced portions and having transverse. sheets engagedand supported thereby and extending transversely therebetween.

It is also an object of the invention to provide a humidifying unitcomprising spaced absorbent sheets having their lower portions submergedin liquid and having a plurality of absorbent sheets engaging the same,along a line and extending therebetween above the liquid.

These. and other objects and advantages of the invention will be fullyset forth in the following description made in connection with theaccompanying drawings, in which like reference characters refer tosimilar parts throughout the several views and in which:

Referring to the drawings, particularly Figs. 1 to 7, a radiator ofrather late type is shown comprising the sections 20 having thesupporting leg portions 20a and the'bosses 202) at the top and bottom,which are arranged in contact for connecting the sections, saidsections'being hollow.

elevation of an absor' The sections, as well understood, carry theheating medium and in the type disclosed said sections are provided witha plurality of vertically extending narrow slots 200, the radiatorillustrated having upper and lower sets of said slots.

In accordance with the present invention, a receptacle 21 is providedadapted to contain a humidifying liquid, such as water, havingthe'desired sterilizing substances in solution therein. The receptacle21 comprises spaced, longitudinally extending, narrow portions 21a andan end connecting portion 2172. In practice, receptacle 21 will beprovided with a supplying and regulating means for the liquid (notshown). Absorbent sheets are disposed in the portions 21a and whilethese sheets might be made in various forms, in the embodiment of theinvention illustrated they are shown as sheets 22 folded along. theircentral same being supported in the portions 21a by having their freeedges received therein. Said sheets 22 are provided with slots 22a intheir folded portions and other. absorbent sheets 23 extend between thesheets 22, being disposed in the slots 22a and extending over receptacle21. The end portions of the sheets 23 preferably extend beyond theremote sides of portions 21a, as shown in Figs. 2 and 3. The receptacle21 is conveniently supported in the radiator-by having the portions 21aextending through certain of the slots 200, as shown in Fig. 3, saidportions resting in the bottom of said slots. With the receptacle sodisposed it is seen that the sheets 23 extend between sections 20 of theradiator, as shown in Figs. 1 and 2. It will be noted that the sheets 23are engaged by the sheets 22 only along a line or lines disposed on saidsheets. A cover 24 is provided which encloses the top andsides of theradiator to a point below receptacle 2]., said cover-having spaced slots24a therein preferably aligned with the spaces between the radiatorsections 20. The cover 24 also preferably has openings in its top, suchas the holes 24b. While the absorbent. sheets 22 and 23 may be variouslymade, one convenient form. thereof is shown. in Fig. 15 and comprisesalayer of metal screen 25, suchas com monly usedin window screens,- oneither, side of which is secured by some suitable adhesive, layer of.blotting paper 26. c

In operation, water, preferably containing a non-volatile disinfectant,such as potassium permanganate, will be supplied to thereceptacle 21 andmaintained at a certain level therein. "The sheets 22 will have. theirlower edge portions disposed in this liquid and will become saturatedwith the liquid due to capillary attraction. The sheets 23 will alsoabsorb the liquid and become well filled with the same. The airpassingupward through the radiator trar'isversely therethrough will engage thesheets 22 and 23 and the receptacle 21 can be'removed after sheets 23are removed, or by lifting said sheets and sheets 22 from thereceptacle. In assembling, the receptacle 21 and sheets 22 will beplaced in the radiator and sheets 23' will then be inserted in placebetween the sections of the radiator. It

is obvious that the absorbent sheets canbe easily and quickly replaced.The humidifier is thus conveniently supported inthe radiator anddisposedin anefiicient position. The same is at the same time not exposed undulyto view sothat a neat structure is produced.

r In Figs. 8 to 12 a different formof radiator is shown' whichis 01' anolder .type and comprises sections 30having bosses 30a which arearranged in contact when the sections are assembled as shown inFig. 8.The receptacle 21 already described is placed on top of the sections 30,portions 21a extending downwardly slightly below the top of the radiatorat the curved upper sides of the radiator sections, as shown in Fig. 9.While the absorbent sheets 22 and 23 could be used, another form of unitis shown disposed in receptacle 21, which unit comprises absorbentsheets 31 extending longitudinally of the portions 21a and upwardlytherein. Slots 31a are formed in sheets, 31 and while these slots mightbe'variously disposed, in the embodiment of the invention illustratedthey are shown as extending diag- "onally downward from the top edges ofsheets 31.

Sheets 31 are shown as having diagonally extending end portions parallelto the slots 31a. Other absorbent sheets 32 are provided, illustrated asof rectangular shape and ashaving slots 32a extends ing thereinto fromone side. posed so as to extend between sheets 31, the slots 32aembracing sheets 31'below slots 31a and the latter embracing the topportions of sheets32. A

huniidifying unit such as shown in Fig. 11 is thus produced and thisunit may be as long as desired or have as many of the sheets 32 thereinas is desired. It will be seen that such a unit can be collapsed intocomparatively fiat form by skew- Sheets'32 are disas shown. Said coverhas a plurality of slots 33a inone side wall and a plurality of openingssuch as the holes 3312 in its top. The sheets 31 and 32 preferably willbe of a construction shown in Fig. 15. f

In operation the liquid used willfbe supplied to receptacle 21 bysuitable means and maintained at a certain level therein. This liquidwill be absorbed by the sheets 31 so that they will become saturated andthe liquid will also be absorbed from the sheets 31 by the sheets 32 sothat the latter will also bev well filled with the liquid. The heat fromthe radiator evaporates the liquid from the sheets 31 and 32, the airmoving upward through and about the radiator coming in contact with saidsheets, particularly the sheets 32 which are disposed across the upwardpath of said air. This air passes outwardly and upwardly through theopenings 33a and 332) so that a circulation of humidified air isproduced. When the cover 33 is removed the units 31 can readily beremoved from the receptacle 21 and new ones placed therein when desired.

From the-above description it is seen that I have provided a simpleandefiicient form of hu-' midifier particularly adapted for usewith aheating radiator. The device has been amply tested in actual practiceand has been very successful. An eifective humidification of the air isproduced.
